A nurse is caring for a 2-year-old with acute laryngotracheobronchitis using a cool mist humidifier. Which of the following findings indicates that the treatment has been effective?
Improved hydration
Decreased stridor
Barking cough
Decreased temperature
The Correct Answer is B
A. Improved hydration is important for managing symptoms but is not directly related to the effectiveness of a cool mist humidifier.
B. Stridor is a hallmark sign of airway obstruction and inflammation in laryngotracheobronchitis. A decrease in stridor indicates that the airways are less inflamed and the child is improving, which is a positive outcome of the humidification treatment.
C. A barking cough is characteristic of croup (laryngotracheobronchitis), and while treatment may help reduce symptoms, it may not resolve completely with the use of a humidifier.
D. While a decreased temperature may indicate improvement in a fever, it is not directly tied to the use of a humidifier. Stridor is a more specific sign of airway improvement in this condition.

Correct Answer is B
Explanation
A. Administering saline drops may be appropriate if there is a foreign body or irritation, but it is not the priority in a case of blurred vision.
B. The priority is to assess the child's visual acuity to determine the severity and possible cause of the blurred vision. This is essential to guide further diagnostic steps.
C. Cleansing the eyes may be helpful if there is visible debris or infection, but it is not the first priority in assessing blurred vision.
D. Obtaining a history is important but would follow after the visual acuity assessment, as it can help provide context for the symptoms.
Correct Answer is C
Explanation
A. Vibration is typically performed during exhalation, not inspiration. This helps to loosen secretions.
B. Percussion should not last 15 minutes per lung segment; it is generally performed for shorter periods to avoid discomfort or injury.
C. Administering albuterol prior to CPT helps open the airways, making it easier for the child to expectorate secretions. This is a standard practice for improving the effectiveness of CPT.
D. It is not recommended to perform CPT immediately after a meal, as it may increase the risk of aspiration or discomfort. It is usually advised to wait at least 30 minutes after eating.
